| Abstract: | The cycloidal gear is widely used in industrial applications, such as gerotor pump, speed reducer, transmission apparatus. A reducer's performance is directly affected by the geometric accuracy of the cycloidal gear. Several measurement methods are used in factories, which measure the deviation of roof-root distance and the length of the common normal line at odd points, and would be difficult to guarantee the accuracy for the whole gear. With the principle of the polar coordinate measurement, a data acquis... |
